Using home equity for business

For a lot of New Zealand business owners, the family home is the most valuable thing they own, and often the only asset a lender takes seriously. Using home equity for business can unlock funding that's faster, larger and more flexible than an unsecured loan. It also means putting your home behind your business, so it pays to do it thoughtfully. This guide explains how to work out your usable equity, what it's commonly used for, how it compares with other funding and how to borrow against your home in a way that protects your family.

It's a well-trodden path. The Reserve Bank's May 2026 Financial Stability Report notes that smaller firms depend on bank and non-bank lending and more often face tougher terms. For owners who can't get what they need on the business's own track record, property is frequently what gets the deal done.

Can you use home equity to fund a business?

Yes. Your home can secure a loan for any genuine business purpose, whether you're a sole trader, a company director, a partner or a trustee. The loan is registered as a mortgage over the home, and the funds go to the business.

With fundU, that usually means a second mortgage behind your existing bank loan, so the home loan stays exactly as it is. If the home is mortgage-free, or you'd rather replace your bank, it can be a first mortgage instead. Loans run from $20,000 to $1m, and the home can be owned by you, jointly with a partner, by your family trust or by a supporting family member acting as guarantor.

What is home equity, and how much of it can you use?

Home equity is the difference between what your home is worth and what you owe on it. Usable equity is the part a lender is prepared to lend against, which is always less than the full amount.

Lenders keep a buffer between total lending and the home's value. That buffer protects everyone if values move, or if a sale takes longer than expected. Here's how to estimate it for yourself:

1. Estimate your home's value. Recent nearby sales and your latest council rating valuation give a rough guide. A lender will use a registered valuation.
2. Find your mortgage balance. Check your latest bank statement or banking app, including any revolving credit or top-ups.
3. Subtract to find your equity. Value minus everything secured against the home.
4. Allow for the lender's buffer. The amount a lender will add depends on the property type, its location and the strength of your exit.

	Example home
Estimated value	$1,000,000
Existing bank mortgage	$480,000
Total equity	$520,000
Usable equity	Less than $520,000, once the lender's buffer is applied
What decides the final figure	Registered valuation, property type and location, and your exit plan

These figures are illustrative only. For a closer look at how lenders size loans, read our guide on how much you can borrow against your property.

What can home equity be used for in a business?

Almost anything that's a genuine business purpose. The most common uses we see are:

• Clearing IRD debt so penalties and interest stop building
• Working capital to cover wages, suppliers or a seasonal gap
• Equipment and vehicles, including second-hand gear that's hard to finance otherwise
• Expansion, such as a second site, a fit-out or new staff
• Funding a big contract where materials and labour are needed up front
• Buying a business, or buying out a partner
• Refinancing expensive debt, such as short-term online loans or merchant advances

If you're buying new equipment, it's worth knowing about Investment Boost. Inland Revenue allows a 20% upfront deduction on the cost of eligible new assets, and assets new to New Zealand, acquired from 22 May 2025. Second-hand New Zealand assets and residential buildings are excluded. Your accountant can confirm what qualifies.

How does home equity compare with other ways to fund a business?

Home equity often allows larger amounts, longer terms and more flexible repayments than unsecured options, but it does put your home on the line. Here's how the main options compare.

Funding option	Security	What it's good for	What to watch
Home equity loan (property-secured)	Mortgage over your home	Larger amounts, flexible repayments, fewer documents with a private lender	Needs a clear exit plan
Bank business loan or overdraft	Often a mortgage over your home anyway	Ongoing, lower-cost facilities for established businesses	Slower, more paperwork, stricter criteria
Unsecured short-term business loan	None, often a personal guarantee	Small, fast amounts	Smaller limits, short terms, frequent repayments
Asset or equipment finance	The equipment itself	Buying specific new equipment	Limited to the asset; less flexible for second-hand gear
Invoice finance	Your debtor book	Businesses with strong, reliable invoicing	Only works if you invoice other businesses

Many owners discover that their bank business loan was secured on their home all along. The real question is often not whether to use home equity, but who to borrow it from and on what terms.

Should you top up with your bank or use a private lender?

If your bank will lend quickly on terms that suit you, a top-up is often the lower-cost choice. If it can't, a private lender can fill the gap.

A private lender like fundU tends to suit owners who:

• need funds within days, not weeks
• have been declined by their bank, or expect to be
• have IRD debt, arrears, defaults or credit issues
• don't have up-to-date financial statements or tax returns
• have irregular or seasonal self-employed income
• want to keep a fixed-rate bank loan untouched

Many owners use private lending for a short period to deal with the immediate need, then refinance back to a bank once the business is on a firmer footing. If the bank has already said no, our page on business loans after a bank decline explains what to do next.

How do you protect your home when borrowing against it?

By borrowing for a clear purpose, sizing the loan sensibly and having an exit you believe in. The owners who use home equity well usually follow a few simple rules:

• Borrow what the business needs, not the maximum available. Unused equity is your safety net.
• Have a realistic exit, and a backup. A sale, a refinance, a contract payment or cash flow, with a plan B if it slips. Our guide to the exit strategy for short-term business loans covers this in depth.
• Match repayments to cash flow. Interest-only or capitalised repayments can protect cash flow while the business recovers or grows.
• Keep the home loan current. Your first mortgage payments should always come first.
• Keep business money separate. Pay loan funds into a business account and track how they're used.
• Talk it through at home. Everyone who lives in the home deserves to understand the plan.

Before you borrow, write down in one paragraph what the money is for, how it will make or save the business money, and exactly how the loan will be repaid. If you can't write that paragraph, you're not ready yet.

What if your home is jointly owned or held in a trust?

That's common and workable. If the home is jointly owned, every registered owner signs the mortgage, and each will sign with a lawyer who explains the documents. If the business belongs to one partner, the other is effectively supporting it, so it's important they're comfortable with the plan.

If the home is owned by a family trust, the trustees provide the security, usually with each trustee signing. The trust deed needs to allow it. Our guide on borrowing against family trust property explains how that works. Parents or other family members can also support a business by offering their property as security, acting as guarantors.

What should you check before borrowing against your home?

A little preparation makes the process faster and the decision clearer. Small businesses make up 97.2% of New Zealand enterprises, according to MBIE, and most of their owners juggle the books around everything else. So here's a short, practical pre-flight checklist:

• Your credit report. You can get your credit report free from each of the credit reporters, Centrix, Equifax and Experian. Check for errors or old defaults you've forgotten about, so nothing catches you off guard.
• Your mortgage statement. Confirm the balance, whether the loan is fixed or floating, and when any fixed term ends.
• Your latest rates notice. It confirms ownership details and gives a starting point for the home's value.
• Your home insurance. A lender will want the home properly insured, so make sure the policy is current.
• Your numbers. Even without formal accounts, a simple cash flow forecast for the next six to twelve months shows how the loan fits.
• Your accountant's view. A quick call can confirm the tax treatment of the loan and any assets you're buying.

None of this needs to be perfect before you enquire. fundU doesn't need financial statements or tax returns for the initial assessment, and our team can help you fill in the gaps.

How does the process work?

With fundU, the process is designed to be quick and straightforward:

1. Make an enquiry online; a short form is all it takes to get started.
2. A lending specialist calls to talk through the home, the business need and the exit.
3. If it fits, we provide indicative terms.
4. A registered valuer values the home.
5. Your lawyer handles the mortgage documents and explains them to each owner and guarantor.
6. Our credit team approves the loan and funds are released at settlement, in as little as 24 hours once approved in some cases.

Example scenario

A Hamilton mechanic running a busy two-bay workshop wanted to add a third bay, a hoist and diagnostic equipment, and hire an apprentice. The bank wanted two years of updated accounts, which were still with the accountant.

The owners' home in Hamilton was worth around $850,000, with a bank mortgage of $390,000. A second mortgage of $180,000 funded the fit-out, equipment and three months of apprentice wages. Interest was capitalised for the first year so the new bay could build up work. The exit was a refinance to the bank once updated accounts showed the extra revenue. This is an illustrative example only.

Key takeaways

• Home equity is your home's value minus what you owe; usable equity is less, after a lender's buffer.
• It can fund almost any genuine business purpose, from IRD debt to equipment, expansion or a business purchase.
• A second mortgage lets you use equity without disturbing your existing bank loan.
• Borrow for a clear purpose, size the loan sensibly and have an exit you believe in.
• Joint owners sign the mortgage; trust-owned homes and family guarantors can also be used.
• fundU lends $20,000 to $1m against New Zealand homes for business purposes.
